Fast, Reliable Roofing Company Across Fresno
If you own a home in Fresno, your roof works harder than most roofs in California. Our summers push past 100°F for weeks at a stretch, and that kind of heat doesn’t just wear roofing material down slowly, it forces shingles, membrane, and flashing through rapid expansion and contraction cycles that split older materials fast. Brennan Roofing Co Fresno operates under The Garrison Standard: a written price before any work starts, background-checked uniformed technicians on every job, and a 365-Day Done Right Promise in writing. We serve homeowners across Fresno, from the 1950s ranches near Manchester Center to newer subdivisions north of the San Joaquin River. Call (559) 785-2160 and a live person answers, day or night.
Why Brennan Roofing Co Fresno Is Fresno’s Preferred Roofing Company Company
Homeowners in Fresno have been burned by roofers who no-show, pad the price at the door, or leave old nails and torn felt scattered across the yard. We built our reputation here on a different approach. Every job gets written pricing up front, and that number does not move at the door. Our technicians are background-checked and arrive in uniform, so when you open the door you know exactly who is about to climb onto your roof.
We work across the whole city. On a 1960s-era home off West Shaw Avenue, our crew opened a wood shake roof that had become brittle from decades of UV exposure, the decking below showed signs of dry rot around old nail holes. We replaced the fire-prone shakes with GAF architectural shingles over new underlayment and drip edge, and we added a ridge vent to reduce attic heat buildup that had been baking the existing roof from underneath. That kind of local knowledge isn’t something a roofer from out of town picks up on the drive in. It comes from working Fresno’s housing stock long enough to know what hides under the first layer.
Brennan Roofing Co Fresno is an independently owned and operated member of the Garrison Partners family, founded in 2000. Phones are answered by a live person around the clock. No voicemail, no automated system.

Free Roof Estimate in Fresno
Free Roof Estimate in Fresno means one of our technicians walks the roof, checks the decking, flashing, and underlayment condition, measures the square footage, and puts the price on paper before any work begins. That’s The Garrison Standard, and there are no exceptions. If you’re seeing granule loss on your shingles, water stains on the ceiling, or your flat roof is starting to show membrane splits at the parapet walls, an estimate tells you exactly what you’re dealing with.
What the Estimate Covers
We look at what’s actually failing, not just what’s easy to see from the ground. That means lifting a few shingles to check the underlayment, walking the flashing around vents and skylights, and checking the drip edge where wind-driven rain sneaks under the starter course. A typical roof inspection or repair estimate in Fresno runs $0 for the visit itself. You get the number in writing before any work starts, and it does not move at the door.
What to Watch For
Fresno’s winter rains expose weaknesses in flashing and underlayment fast. If you’ve got a low-slope roof common to 1960s homes in central Fresno, hairline splits at roof-to-wall transitions can let water in without ever showing a shingle out of place. A free estimate catches those before a small reseal becomes a decking replacement.
Roofing Contractor in Fresno
A Roofing Contractor in Fresno has to know what this climate does to specific materials. Thirty-plus days over 100°F every year means asphalt shingles bake and crack through thermal shock, which is exactly what we see on homes across the Tower District and Sunnyside. Membrane roofs on flat and low-slope homes split at the roof-to-wall joints within two summers when they’re installed without proper allowance for expansion. That’s a Fresno problem, not a coastal one.
Repairs and Replacements Done Right
We handle roof repair, full roof replacement, and roof inspection across the city. A common repair call is wind-driven rain breaking through at the drip edge because the original installer skipped the starter strip along the eaves. Underlayment wicks the water up, and before long you’ve got a ceiling stain that keeps coming back. We pull the affected material, repair or replace compromised decking, and reinstall with the starter course done properly.
Flat and Low-Slope Roofs
Fresno’s huge stock of 1950s to 1980s homes includes thousands of low-slope and flat roofs using built-up roofing or composition shingles. These roofs fail differently than steep pitches. They pond water in the wet months, cooks in the summer, and the membrane moves. We install and repair built-up roofing with attention to expansion joints, parapet flashing, and drainage, so the repair lasts longer than two summers.
Trusted Brands We Service in Fresno
We install materials from manufacturer lines including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so if another roofer put on a specific shingle, we know its profile and can match or upgrade it. CertainTeed architectural shingles hold up well against thermal shock when we pair them with proper attic ventilation, and Tamko’s cool-roof line is a real option for north Fresno homeowners tired of paying to air-condition their attic twice. We explain the differences in plain English, give you the real price on paper, and let you choose.
Common Roofing Company Problems We See in Fresno Homes
- Thermal shock cracks in asphalt shingles. Thirty-plus days over 100°F bake the asphalt until it loses flexibility, then the fast overnight cool-down cracks the surface. Those hairline splits let water in during the winter downpours and they don’t reseal.
- Membrane splits on flat built-up roofs. Roof-to-wall transitions fail when expansion isn’t accounted for at installation. We reseal or replace with proper expansion allowance so the repair doesn’t fail next summer.
- Brittle wood shake roofs on the west side. Many 1960s-era homes still have original shakes that have been UV-baked into kindling. They’re fire-prone and the decking underneath is often dry-rotted around old nail holes. Replacement, not repair, is usually the honest call.
- Wind-driven rain at the drip edge. Missing or improperly installed starter strips along eaves let water break through during winter storms in northwest Fresno. The shingles look fine from the ground; the leak is at the edge.

FAQs About Roofing Company in Fresno
The crack comes back because the membrane wasn’t installed with enough allowance for thermal expansion. Fresno’s summer heat makes the membrane expand and push against the parapet transition; when it cools, it contracts and tears. We strip the transition, install new flashing and membrane with proper room to move, and the repair holds. Call (559) 785-2160 and we’ll look at your parapet joints in person.
In nearly every case, replacement is the honest answer. Decades of UV exposure leave the shakes brittle and fire-prone, and the decking underneath is usually dry-rotted around old nail holes to the point where new shakes can’t hold. We’ll walk the roof with you, show you what the decking actually looks like, and give you a written price for replacement with modern architectural shingles. Call (559) 785-2160 for a free estimate.
One square equals 100 square feet of roofing surface. A roofer quoting 18 squares is covering 1,800 square feet. We write our quotes in both, so you can compare apples to apples. But the bigger issue in Fresno is comparing scope. Does the quote include tear-off, decking repair, drip edge, underlayment, and flashing? A lower per-square number that skips decking replacement will cost more when rot spreads. Get the line items. We put everything on paper before any work starts.
Ice and water shield isn’t about snow in Fresno, it’s about wind-driven rain. Winter storms push water sideways against eaves, valleys, and penetrations. Without a self-adhering underlayment at those points, water wicks under the shingles and finds the decking. We install ice and water shield at eaves, valleys, and around penetrations on every re-roof because the Fresno weather that matters is rain, not snow. Call (559) 785-2160 and we’ll explain exactly where it goes on your roof.
Yes, and in north Fresno where every subdivision faces the afternoon sun, the reduction in attic heat is measurable. Cool roof shingles reflect more sunlight and re-emit heat faster than standard shingles. The attic runs 20 – 30°F cooler in July, and that means your air conditioner isn’t fighting a 140°F attic blanket. The upgrade adds roughly $1,200 – $2,500 over standard shingles depending on roof size. Call (559) 785-2160 and we’ll give you the exact number for your roof.
